  Purpose
Based on the radiobiological findings that accelerated tumor repopulation in nasopharyngeal carcinoma occurs in the late-course of radiation therapy, the investigators hypothesize that intensity-modulated radiation therapy(IMRT) with concomitant boost schedule by increasing daily dose starting at the fifth week after initiation of IMRT might improve tumor control and decrease treatment toxicities for locoregionally advanced nasopharyngeal carcinoma. The study is designed to test if late-course accelerated hyperfractionated IMRT can improve the outcomes as compared with conventionally fractionated IMRT in newly diagnosed patients with locoregionally advanced nasopharyngeal carcinoma.

Condition Intervention Phase
Nasopharyngeal Carcinoma Radiation: Late-course accelerated hyperfractionated IMRT Drug: Concomitant cisplatin chemotherapy Radiation: Conventionally fractionated IMRT Phase 2 Phase 3

Arms Assigned Interventions
Experimental: A
Late-course accelerated hyperfractionated IMRT with concomitant cisplatin chemotherapy
Radiation: Late-course accelerated hyperfractionated IMRT
  1. IMRT target definition: PTV1=Gloss tumor PTV; PTV2=High risk area containing subclinical disease; PTV3=Low risk area containing subclinical disease
  2. IMRT delivery scheduling: (1) Six-week treatment: PTV1=60Gy/30fractions, PTV2=57Gy/30fractions,PTV3=54Gy/30fractions.(2) Concomitant boost to PTV1 as a second daily treatment for the last 10 treatments of the Six-week treatment: PTV1=12Gy/10fractions.(3) PTV3 will be treated with conventional radiotherapy technique separately.
Drug: Concomitant cisplatin chemotherapy
cisplatin:40mg/m2 weekly infusion for 6 weeks
B
Conventionally fractionated IMRT with concomitant cisplatin chemotherapy
Drug: Concomitant cisplatin chemotherapy
cisplatin:40mg/m2 weekly infusion for 6 weeks
Radiation: Conventionally fractionated IMRT
IMRT target definition: PTV1=Gloss tumor PTV; PTV2=High risk area containing subclinical disease; PTV3=Low risk area containing subclinical disease IMRT delivery scheduling: (1) Seven-week treatment: PTV1=70Gy/35fractions, PTV2=63Gy/35fractions,PTV3=55.8Gy/31fractions.(2) PTV3 will be treated with conventional radiotherapy technique separately.
